BUTTON.

SPECIFICATION forming part of Letters Patent No. 378,923, dated March 6, 1888.

Application filed October 28, 1887. Serial No. 253,582. (No modei.)

T0 aZZ whom. it may concern.-

Be it known that I, SHUBAEL COTILE, of the city, county, and State of New York, haveinvented a new and useful Improvement in Stud, Collar, or Sleeve Buttons, of which the following is a specification.

In Letters Patent No. 311,107, granted. to me on the 20th day of January, 1885, I have fully described and broadly claimed a collar-button having a back and post formed of the same piece of sheet metal, in which the back is double. In the embodiment of my said invention,illustrated in said Letters Patent, I show a button having a cylindrical closed post and double base with an opening in the center of the base, and ma modification thereof 1 show a button having a double base without an aperture and a cylindrical post open at its upper.

end.

My present invention relates to a stud, collar, or sleeve button of the same general type as that disclosed in my aforesaid Letters Patent, but of a different construction. It is integrally made in all its parts from ahollow continuous closed shell of metal that is, a shell in which there are no openings. The base or back is formed of a double thickness of metal, and in the center of the bottom plate is a convex portion which serves as a brace or stay to prevent deformation of base or post.

In the accompanying drawings, Figure 1 is a longitudinal section of my new stud, collar, or sleeve button on the line x m of Fig. 3. Fig. 2 is a side elevation. Fig. 3 is a top view, and Fig. 4 is a bottom View, of the same.

Similar letters of reference indicate like parts.

My button is composed of a head, A, a shank or post, B, and a base or back, 0. I produce it integrally from a hollow continuous closed shell of metal, sothat in the completed button, as shown in Fig. 1, there is no opening whatever. This I may do by any suitable methodsuch, for example, as follows: I first produce a blank in the form of a short tube of sheet metal closed at one end. compressing said tube in suitable dies, a depression about midway the length of the tube. The part so depressed forms the shank B of the finished button. I then place the button in a lathe, and by means of suitable spinning- I then produce, by

tools flatten the closed extremity thereof, so as to form the fiat back or base 0. The tube onthe opposite side of the shank B still being open, the button isreset in the lathe, and by means of a spinning-tool the circumferential edge of metal around the opening is bent inwardl y until said opening is gradually reduced in diameter and finally closed altogether. The head A of the button is thus completed.

The aforesaid process of manufacture I have fully described and claimed in another application for Letters Patent filed on December 9, 1887, Serial No. 257,384, and now pending. The said process'is therefore herein disclaimed. The flange of the base 0 of the button is here shown of double thickness of metal, and is formed by bringing the annular upper plate, a, and the disk-shaped lower plate, I),

- both being parts of the same shell, into close proximity. In the center of lower plate, I), of the base is formed a convex portion, 0, which comes directly opposite the hollow in the post. Around this convex portion 0 is a depression, d. By this means the portion of plate I) outside the convex portion 0 is made to conform to the shape of plate a, and close contact between the plates a and b is secured at the circumference of said convex portion. Said con vex portion 0 thus acts as a bridge, stay, or support at about the point of meeting of the hollow post B and annular plate a of the base (J, and serves to prevent peripherical deformation of the post and any tendency of distortion of the base from its proper plane when strain is applied to said base or post. The lower disk-shaped plate, b, of the base being in a single piece, also acts as a stay to resist any tendency of the hollow post B to open or spread when the button islongitudinally compressed.

ton has everywhere a uniformly smooth exter101.

I claim- 1. A hollow stud, collar, or sleeve button formed of a single piece of thin metal and without an opening into its interior, substantially as described.

2. A stud, collar, or sleeve button having a head, a shank or post, and a base, and integrally formed of a hollow continuous closed metallic shell, substantially as described.

3. A stud, collar, or sleeve button having a head, a shank or post, and a double back or base, and integrally formed of a hollow continuous closed metallic shell, substantially as described.

4. A stud, collar, or sleeve button integrally formed of a hollow continuous closed metallic shell having a head, a shank or post, and a double back, the said double back comprising an annular upper plate and a disk-shaped lower plate, substantially as described.

5. A stud, collar, or sleeve button integrally formed of a hollow continuous closed metallic shell having a head, a shank or post, and a double back, the said back comprising an annular upper plate and a disk-shaped lower plate, and at the center of said lower platea convex brace or stay, substantially as described.

6. A stud, collar, or sleeve button integrally formed of a hollow continuous closed metallic shell and having a head, A, shank B, and base 0, the said base being composed of the parts a and b, and in the part b the convex brace or stay 0 and surrounding depression d, substantially as described.
